A strong 7.0-magnitude earthquake has struck eastern Russia's Kamchatka Peninsula, the U.S. Geological Survey says.
The quake occurred on the morning of January 30 at a depth of 160 kilometers, about 95 kilometers northeast of the Russian town of Yelizovo, it said.
The National and Pacific Tsunami Warning Centers said there was no risk of a tsunami and there were no immediate reports of damage or injuries.
The Russian Academy of Sciences said on its website the first tremor was followed minutes later by a 5.2-magnitude aftershock.
Russia's Kamchatka Peninsula sits on the so-called Pacific "Ring of Fire," an arc of fault lines that circle the Pacific Ocean and are prone to frequent, large earthquakes and volcanic eruptions.
